Function
Sets the data transfer times when the "Event
that the specified number of data are transferred" is used.
This settings is necessary when the transfer mode of the conversion data
that is set by AioSetAiTransferMode function is User buffer mode.
This function needn't be executed if the transfer mode of the conversion
data is Device buffer.
Format
Ret = AioSetAiEventTransferTimes ( Id , AiTransferTimes )
Parameters
Id
[ C, C++ : short ] [ Python : ctypes.c_short ]
Specifies the Device ID retrieved from AioInit function.
AiTransferTimes
[ C, C++ : long ] [ Python : ctypes.c_long ]
Sets the data transfer times that cause the event to raise.
Return value
Ret [ C, C++ : long ] [ Python : ctypes.c_long ]
